The ongoing partial federal government shutdown could be a boon to some charities. Several members of Congress have pledged their salaries to charities during the shutdown. A member of the U.S. House of Representatives or U.S. Senate typically earns $174,000 per year (which works out to about $725 per day, based on a five-day work week, not counting holidays).

The shutdown affects about one-fourth of the federal government and began on Dec. 22 after President Donald Trump refused to sign a spending bill that did not include $5 billion for a wall along the U.S. border with Mexico. About 420,000 federal employees are working without pay while another 380,000 have been furloughed. It doesn’t include employees of vendors contracted to work for the federal government.

Sen. Elizabeth Warren (D-Mass.), who is exploring a 2020 presidential run, pledged her salary to HIAS, a nonprofit that assists refugees. She tweeted on Jan. 1 that more than 7,000 people in her state are currently at home or working without any salary.

Over 7,000 people in Massachusetts have been sent home or are working without pay during the #TrumpShutdown. Until @realDonaldTrump re-opens the government, I’m donating my salary to @HIASrefugees, a nonprofit that helps refugees and makes our country stronger in the process.

Sen. Catherine Cortez Masto (D-Nev.) also tweeted last month that she would donate her salary to a Nevada charity for each day the shutdown lasts but did not specify a particular organization.

I cannot take a salary during a government shutdown knowing that so many federal workers in Nevada and across the country will go without pay. I’ll be donating my salary to a Nevada charity for every day of the Trump shutdown.

In a Tweet, Congressman-elect Max Rose (D-N.Y.) said, “…it’s time for us to do our jobs, and until we do I will donate any pay” but did not specify a charity. SILive.com reported that Rose will donate his salary to a New York-based nonprofit that helps individuals dealing with opioid addiction.

Until the #TrumpShutdown is done, all my pay will be going to Homes For The Brave (@ABRI_HFTB) benefiting CT veterans. Least I can do.

Sen. Richard Blumenthal (D-Conn.) was the latest to pledge his salary, with a statement today that he would give to the Homes for the Brave, a Bridgeport, Conn.-based charity that provides housing and services to people experiencing homelessness, particularly veterans.
